Class Thermodynamics

This curricular unit belongs to the curricular plan of this 1st cycle degree, whose concepts taught are important for the acquisition of knowledge of subsequent curricular units. This course aims to provide students with fundamental knowledge of thermodynamics and heat transfer. The basic principles of thermodynamics and its mathematical formulation will be developed, as well as some of the main applications. More specifically, concepts related to pure substances, the 1st and 2nd laws of thermodynamics and the power and cooling cycles will be given. The basics of heat transfer processes will also be covered.

Not applicable

UNITS AND CONVERSIONS.   CONCEPTS: Thermodynamic system. State and transformations. Forms of energy. Specific heat.   PURE SUBSTANCE: behavior and properties of a pure substance; the ideal-gas equation of state.   1st LAW OF THERMODYNAMICS: energy transfer in the form of heat and work; energy balances; internal energy and enthalpy.   2nd LAW AND ENTROPY: thermal engines; Kelvin-Planck statement; efficiency of thermal machines; reversible processes. Carnot cycle; the quality of energy. Clausius inequality; entropy.   POWER AND REFRIGERATION CYCLES: Rankine, Otto, and Brayton cycles; vapor compression refrigeration cycle; heat pump.   HEAT TRANSFER: Conduction: Fourier's Law; conductivity and thermal resistance. Convection: Newton's law of cooling; convection transfer coefficient. Radiation: Stefan-Boltzmann's Law; overall heat transfer coefficient.

Despite the fundamental nature of the subjects involved in this UC, as well as the classical perspective with which they are approached, whenever possible, innovative teaching methodologies will be used, namely Problem-Based Learning (PBL).
